# BMS vs Lucky PV

The clearest difference is review sentiment: Lucky PV at 67% against BMS's 20%. Lucky PV also leads on update cadence (monthly vs every 2 months) and ratings volume (3 vs 1). BMS's advantage is rating (5.0 vs 4.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

BMS holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 1 and 3 respectively. Written reviews complicate that: 20% of BMS's written reviews are positive against 67% of Lucky PV's, so the app with the better star average is not the one people write more warmly about.

BMS ships an update every 2 months, Lucky PV monthly. Both last shipped on October 10, 2026.
